There was the classic case where he said he was such a free speech absolutuonist that he wouldn't ban the person who was tracking his plane. Guess what happened shortly afterwards

you would have received more relevant responses if you had titled your post as, "there is absolutely no evidence that musk is against free speech. what are you folks on about, anyway?"

I wouldn't bother. People who arrive at any opinion without using logic can't be reasoned out of that opinion using logic. It's an emotional thing.

As for your original question: Musk helps oppressive states enforce censorship on his platform .

His passion for free speech is only for white supremacists and conspiracy theorists now running rampant on his platform (there is a John Oliver segment about it).

He opposed an anti-hate-speech law in Ireland, although the law makes clear that it is still allowed to express unfavorable opinions and offend others, but forbids incitement to violence.

This shows he is not interested in defending "unfavorable reasoning" against the "woke" inquisitors, rather than advancing hate-speech and white supremacist causes in particular. This is not only a hypothesis, but a reported outcome of his actions with X/Twitter, which is now a nazi bar.

Don't forget Russel's tolerance paradox: If you tolerate nazis in order to defend freedom (of speech, political association, and the like), they will overtake the state apparatus and verbot freedoms for everyone, not only speech, but freedom of life as well.

He is doing exactly that, not only permitting, but promoting white supremacy, and at the same time treating the term "cisgender" for example as a slur.

This shows he is not all in for defending free-speech for all sides, but he is out to "destroy to woke mind virus" because it "stole his son from him".

Musk is a nazi apologist, a big cry baby, and a media gatekeeper who enforces censorship both as a platform owner and as a service to totalitarian states.

He is a national security risk, according to Wired.

Assuming your intentions are genuine and this isn't a trolling attempt, I would suggest you start with a web search for "musk free speech hypocrite". Plenty of articles out there.

Good luck with your father.

The Hyperloop still hasn't happened in an age where we can grab rockets from the sky.

It was just a great idea to stop development of high-speed rail so cars could still make sense for longer.

Hopefully USA seems to be realising already: https://techcrunch.com/2023/12/22/hyperloop-one-elon-musk-high-speed-rail/

The more useful framing might be someone like Ford.

I'd be hard pressed to argue Musk hasn't had some sort of a hand in a couple significant technological movements (Tesla, SpaceX) but that doesn't make his political positions worthy of respect.

Similarly, for all his flaws, Ford revolutionized the factory. That didn't make his Brazilian city work, his shitty anti semetic views right or his "meh" attitudes on ww2 correct.

Musk's successes don't particularly quality him on everything.

This man likely wants to be president, but cannot, so he’s riding the Trump train instead. As such, I suspect you can find him bending on free speech and leaning into incitement of more Jan 6 treason quite a bit in regards to that personal motive.

You can't reason with an irrational opinion. I applaud you for trying, but don't blame yourself if it doesn't work.

I doubt you'll find any proof that he is against free speech. More like, he cares about other things more than he cares about free speech. Such as his bank account.
